The Astringency of GSOR Iterative Algorithm and BGSOR Iterative Algorithm

摘要

This article uses the iterative algorithm of Generalized Succesive Over Relaxation (GSOR)and Block Generalized Succesive Over Relaxation (BGSOR), discussed the astringency of the solution system of linear equations's GSOR iterative algorithm and BGSOR iterative algorithm. When parameter matrix Q=diag(ω1,ω2...,ωn)=ωIn, then obtains the knowledge SOR algorithm, is to the SOR iterative algorithm and the Block SOR iterative algorithm astringent promotion.
